Enclosing class:

LibMatrixDNNConv2dHelper

public static class LibMatrixDNNConv2dHelper.LoopedIm2ColConv2dTransAllChan
extends LibMatrixDNNConv2dHelper.LoopedIm2ColConv2dAllChan

This implementation is similar to LoopedIm2ColConv2dAllChan, except for using a sparse-dense matrix multiplication with t(t(Xi) %*% t(F)) instead of a dense-sparse matrix multiplication with Xi %*% F. NOTE: this implementation assumes that the filter is passed in transposed form in order to share this temporary matrix (and its creation cost) across threads.
